Wind farms are supposed to be environmentally friendly, but research reported in Nature indicates that large wind farms actually contribute to warmer temperatures, at least at the local level. At nighttime, after the sun goes down, the earth’s temperature usually decreases. Large wind farms mix that cold air with warmer air aloft, increasing the local temperature. This could have an eventual effect on wildlife in the area and could also affect the weather regionally, since warmer air contributes to cloud formation and wind speeds. The research was done in Texas, which has four of the largest wind farms in the world. China is reportedly erecting 36 wind turbines a day (Telegraph, April 29).

Writing about Prison Fellowship, founded by the late Chuck Colson, Mark Oppenheimer points out that there have been two impulses behind incarceration in the U.S. One, with Christian underpinnings, focused on reforming the imprisoned; the other, which took hold especially in the South during the era of slavery, promoted harsh living conditions and punitive labor (think chain gangs and labor farms). Colson advocated for less crowded, more humane prisons. His critics say that Prison Fellowship doesn’t challenge the prison system so much as work toward the spiritual reformation of individual prisoners. Studies are mixed on whether such a ministry turns prisoners away from a life of crime once they’re back on the street (New York Times, April 27).

Flora Slosson Wuellner witnessed a congregational business meeting in which deliberations would cease after every half hour and the congregation would sit in silence for five minutes, attending to the Spirit’s promptings. People would take turns holding a stopwatch. After the silent periods, “the tone of the talk and planning changes, attitudes changed, disagreements were handled differently, fresh options were envisioned,” Slosson Wuellner says (Weavings, May).

Baseball commentator Tim McCarver has been ridiculed for suggesting that global warming is to blame for an increase in the number of home runs hit in the major leagues. To a point he’s correct. Balls carry better in warm, humid air. The increase in global temperature does track with an increase in home runs. However, other factors are involved, including changes in athletic ability, batting and ball technology and pitching styles. One physicist argued that a two-degree rise in temperature could lead to a 1.75 percent increase in home-run odds. A climatologist argued that an increase in carbon emissions makes the atmosphere heavier, which should result in fewer home runs (Washington Post blog, April 30).

The Vietnam War underscored for Ismael García the colonial status of Puerto Rico. An inordinate number of Puerto Ricans were drafted to fight that war, even though they couldn’t engage in electing the people who were responsible for it. García was also disappointed in the church at the time, because he thought it ignored social and political realities on the island and focused instead on whether it was appropriate for women to wear slacks and how long men’s hair should be. In time García, who became a Christian ethicist, discovered Christians who modeled a life of social activism and inner spiritual devotion. He identified three traits of these Christians: they view God as sovereign in all spheres of life; they are committed to projects and concerns larger than their own personal interests; and they know that faithful living entails social analysis and cultural interpretation (“On Spirituality,” in A Spiritual Life, edited by Allan Hugh Cole Jr., Westminster John Knox).
